| 摘 要： | 为了调整微量元素在种植棉花的土壤中的含量，以及提高施肥的精度，最终达到保护环境质量和农业资源的目的。笔者在GPS野外定位、量取样品、分析样品等步骤的基础上，获取了土壤属性数据。运用相关分析模块和统计分析模块，将渭-库河绿洲的种植棉花的土壤作为研究对象，分别分析了土壤中的有机质和pH与四种微量元素之间的相关性特征。结果表明：该研究区中的土壤有机质与有效铁和有效铜呈极显著负相关关系，相关系数分别为-0.557和-0.458，而与有效锰和有效锌之间的相关性不明显，均没有达到显著水平。土壤pH与有效锰呈极显著负相关关系，相关系数为-0.406，与有效锌呈显著负相关，相关系数为-0.274。在生产过程中，应该根据研究区土壤的性质，在合理使用有机肥的同时，适当调节土壤酸碱度，平衡作物中的营养物质，有利于各种作物对微量元素的吸收，从而提高农作物的产量以及质量，保证西北干旱区农业生产的可持续发展。

| Abstract: | To adjust the content of trace elements in cotton planting soil, and improve the accuracy of fertilization, thus to achieve the purpose of protection of the environmental quality and agricultural resources, the authors obtained the properties data of the soil based on field GPS location, sample measuring and analysis. Using Ugan-Kuqa river oasis cotton soil as the research object, the authors analyzed the correlation between soil organic matter, pH value and four kinds of trace elements by the method of correlation analysis module and the statistical analysis module. The results showed that organic matter was significantly and negatively correlated with available iron and available copper, and the correlation coefficient was -0.557 and -0.458, respectively, while its relationship with available manganese and available zinc was not obvious, which did not reach the significant level. Soil pH value was significantly and negatively correlated with available manganese, and the correlation coefficient was - 0.406, and was negatively correlated with available zinc, and the correlation coefficient was -0.274. In the process of production, we should reasonably use organic fertilizer,adjust soil pH value, and keep nutrients in crops balance according to the nature of soil in the study area, and it would be beneficial to the absorption of trace elements, and increase crop yield to ensure the sustainable development of agricultural production in the northwest arid areas. |
